Answer:

Step-by-step explanation:

Alexis is X years old

Josiah is X + 5 years old

in 7 years:

Alexis is x + 7 years old

Josiah is x + 5 + 7 => x + 12 years old

Sum of their ages is 85 :

x + 7 + x + 12 = 85

2x + 19 = 85

2x = 85 - 19 = 66

x = 66/2 = 33 => Alexis age

Josiah is x + 5 = 33 + 5 = 38 years old

Answer:

A. 94.37 seconds

B. 0.48 seconds

Step-by-step explanation:

Total distance = 50 meters

First trial = 32.15 seconds

Second trial = 31.67 seconds

Third trial = 30.55 seconds

A. What is Todd's combined time for all three trials

Todd's combined time for the three trials = First trial + Second trial + Third trial

= 32.15 seconds + 31.67 seconds + 30.55 seconds

= 94.37 seconds

B. How much faster was Todd's second trial than his first trial?

Second trial = 31.67 seconds

First trial = 32.15 seconds

Time taken for first trial - Time taken for second trial -

= 32.15 seconds - 31.67 seconds

= 0.48 seconds

Todd's second trial was 0.48 seconds faster than his first trial

Answer:

it's 42 my bad...

Step-by-step explanation:

Answer:

Choice C 42 in^2

Step-by-step explanation:

Area of a triangle= 1/2(b)(h)

= 1/2(3)(6)

= 9

Since there is two triangles we can do:

9(2) = 18

Area of a rectangle = (b)(h)

= (4)(6)

= 24

24+18 = 42 in^2

Answer:

[0, ∞)

Step-by-step explanation:

The domain is the x values in a function. As you can see from the graph, the function touches zero (touching meaning the value zero is bracketed) and goes to infinity (infinity is parenthesis).

If a value is included it is bracketed. If it is not included it is used with parenthesis (infinity cannot be reached to it is used with parenthesis).

Equality Properties

Step-by-step explanation:

Step 1: Define equation

5(x - 8) = 20

Step 2: Solve for x

Step 3: Check

Plug in x into the original equation to verify it's a solution.

Here we see that 20 does indeed equal 20.

∴ x = 12 is a solution to the equation.

[tex]\left(x_1,\:y_1\right)=\left(-5,\:-1\right),\:\left(x_2,\:y_2\right)=\left(6,\:-2\right)[/tex]

[tex]=\left(\frac{6-5}{2},\:\frac{-2-1}{2}\right)[/tex]

[tex]=\left(\frac{1}{2},\:-\frac{3}{2}\right)[/tex]

Thus, the coordinates of the midpoint of the line segment p(-5,-1) Q(6,-2) would be: (1/2, -3/2)

Answer:

we would add [tex]\:\left(\frac{1}{2}\right)^2\:[/tex] or 1/4 to make the expression a perfect square.

Step-by-step explanation:

Given the expression

[tex]x^2+x[/tex]

[tex]\mathrm{Write}\:x^2+x\:\mathrm{in\:the\:form:\:\:}x^2+2ax+a^2[/tex]

[tex]2a=1[/tex]

Divide both sides by 2

[tex]\frac{2a}{2}=\frac{1}{2}[/tex]

[tex]a=\frac{1}{2}[/tex]

as

[tex]x^2+2ax+a^2=\left(x+a\right)^2[/tex]

[tex]\mathrm{Add\:}\:\left(\frac{1}{2}\right)^2\:[/tex]

[tex]x^2+1x+\left(\frac{1}{2}\right)^2=\left(x+\frac{1}{2}\right)^2[/tex]

Thus, we would add [tex]\:\left(\frac{1}{2}\right)^2\:[/tex] or 1/4 to make the expression a perfect square.

Answer:

a = 3

Step-by-step explanation:

Calculate the distance d using the distance formula and equate to 4

d = [tex]\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2 }[/tex]

with (x₁, y₁ ) = (2, - 1) and (x₂, y₂ ) = (2, a)

d = [tex]\sqrt{(2-2)^2+(a+1)^2}[/tex] = [tex]\sqrt{0+(a+1)^2}[/tex] = [tex]\sqrt{(a+1)^2}[/tex] = a + 1 then

a + 1 = 4 ( subtract 1 from both sides )

a = 3

Answer:

A. coefficient

Step-by-step explanation:

A constant is the number that isn't with any variable, which in this case, the constant would be 15.

A variable is a unknown value, which in this case, the variable would be x.

The term are the numbers in the equation, which in this case, the terms would be 7x and 15.

The 7 in the expression 7x + 15 is the coefficient.

The correct option is A.

A term is composed of one mathematical expression. A single variable (a letter), a single integer (positive or negative), or a number of variables that have been multiplied but never added or subtracted are all examples of single variables. There is a number in front of certain words that are variables. A word or phrase is preceded by a coefficient.

In general, a coefficient is the numerical factor of a term that contains a variable. In this case, the term containing the variable x is 7x, and the coefficient of this term is 7. The term 15 is a constant term, which is a term that does not contain any variables.

Answer:

Finding the y value is easy if you know the slope of the line and the x coordinate. Review the equation for the slope of a line. The equation for finding the slope is: m = [y1 - y2] / [x1 - x2]. If you know x, you can solve for y to find the y value for the slope of the line.
